Satellite -- A satellite is an object that orbits another object.
With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite.
In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...
